15 Claims. (01. 206-56) The invention relates to holder-containers forcosmetic crayons and other material of like manner of use, the objectbeing the general improvement of such devices in respect of compact- 5ness, ruggedness and appearance.

In the drawings which illustrate the preferred form of the invention,

Fig, l is a perspective elevation of the devi approximately life size; LFig. 2 is a longitudinal section of line 11-11 of Figure I, greatlyenlarged for sake of clarity;

Fig. 3 is a partial longitudinal sectional view at right angles toFigure 2;

Fig. 4, a section on IV-IV of Fig. 8; I Fig, 5, an elevation of therotarysleeve;

Fig. 6, the fiat blank of which it can be formed; Fig. 7, an elevationof the main or outer cylinder;

Fig. 8, a partial cross-section showing the thumb piece and its keeper;

Fig. 9 a similar view of the inner cylinder.

The outside cylinder being in the present case the enamelled orornamental casing of' the device is marked I and is ahollow cylinderwhich may be conveniently drawn out of brass stock. 25 It is providedwith a longitudinal slot 2 for-a traveller button or thumb piece 3 whichis retained 'in the slot by a small curved plate or keeper 4, see Fig.8. When the cylinder is held in the fingers, the button 3 can be pushedback and forth with the thumb, being thus a one hand device. The casingis shown detached in Fig. '7. Next within the casing or main cylinder Iis an inner rotary sleeve 5 connected to the button 35 3 by its spiralslot 6 so that the rectilinear mo'vemcnt of the button 3 rotates thesleeve relatively to and within the main cylinder I. Next within therotary sleeve 5 is an inner cylinder I (Fig. 9) which is expanded at its40 base and there secured in a permanent manner to the base endvoi theouter casing I. The junction of these two cylinders is covered over by acap 8 which constitutes the bottom end closure and reinforcement of thedevice. It can be a pressed-fit thereon as indicated. The rotary sleeve5 rotates in the annular space between the two united cylinders I and Iand is retained against excessive endwise movement 50 therein by a stud9 riveted in the inner cylinder I and engaging an arcuate slot III inthe'lower part of the rotarysleeve 5. This rotary sleeve can be'made ofa fiat sheet or blank, punched as shown in Figure 6 and rolled to thecylindrical 5 form indicated by Figure 5,'the meeting edges of the blankbeing locked together by the tongue and notch formation indicated by IIand be- V tween them forming another spiral slot, presently referred toas the slot I6.

Next within the fixed sleeve I is the sliding 5 cup or carrier I2 whichholds the crayon I3 in any suitable way as for example by friction, thecrayon being merely pressed into the cup when the holder is open. Thecarrier is merely an open ended tube with one or more inbent tabs 10 I2punched and bent out of its wall to form a seat for the crayon. It isprovided with a stud I4 riveted thereto and adapted to ride in thelongitudinal slot I5 formed in the inner fixed cylinder I and this studI 4 projects through the 5 straight slot I5 into a second spiral slotI6, also formed in the rotary sleeve 5, this being the slot formed bythe proximate edges of the rolled blank. The rotation of sleeve 5 movesthe carrier up and down, the carrier being held against rotation by itsstud engagement with the slot I5 of the relatively fixed cylinder 1.Preferably downward movement of the thumb piece 3 rotates the ,sleeve 5in the direction to raise the can'ier toward the open end of the holderalthough this arrangement is not essential and could be reversed ifdesired and other forms of thumb-operated members could be provided forconverting the thumb movement into rotary movement of the sleeve.

The closure mechanism of the holder is of the disappearing door type andcomprises two quarter-spherical thin shelves or stampings I1 and I'lwhich are duplicates of each other and pivoted inside the holder toswing toward and from each other om a common transverse axis.

The end of the outer cylinder I is spherically tapered or inbent at itsend to form a curved annular flange I which somewhat reduces thevdiameter of the open end of the cylinder. The 40 two door members houseunder this fiange when opened, their paths of movement being close toand substantially concentric with the spherical taper. While the doon.members may be otherwise mounted and otherwise operated, it is preferredto pivot their hub portions on the two upstanding posts I8 which risefrom the upper end 0! the inner cylinder I and these pivots areconveniently formed as e elets I9 integrally stamped or drawn out of thematerial of the posts I8 themselves. Each door member hub is cut orstamped with a pair of gear teeth marked 20 and 20' respectively andthese teeth directly overlie the top edge of the rotary sleeve 5 and arearranged to be engaged by corresponding 5 teeth 2i and 2| cut in suchtop edge, there being two teeth 2! on one side of the sleeve, and two,2|, on the other. The doorsand their teeth are punched out of relativelythin sheet stock and the combined thickness of their hubs 15811011;equal to that of the sleeve. The teeth are arranged in such manner thatrotation of the sleeve swings the two members toward orfrom each other,closing them together on the center line of the device, and opening themto positions under the flange, i. The doors are opened by the initialmovement of the sleeve 5 after which one of the teeth on each doormember rides along on the smooth top edge of the sleeve, thus holdingthe member open. on return of the sleeve to itsinitial position, thedoor teeth are picked upagain by the sleeve teeth and thereby restored.to closed position.v

This action is timed so that the doors are open at the proper point topermit the crayon to protrude and are closed after it has recededthrough the door opening-r- 1 While it is desirable that the doorsegments shall operate close to the inner face of the spherical flange Ithus to make a tight dustexcluding closure, it is also important thatthey shall not rub or bind thereon at least to such an extent as tointerfere with their free action and make the device diflicult tooperate. Such binding eflect unless prevented is likely to oc-' cur fromdistortion, under the pressure of the user's thumb of the casing I. Thisas well as the other cylinders are made of the thinnest practicalsection for the sake of lightness of weight, and economy of material,the rotary sleeve being the thickest member on account of its teeth andthe work it has to perform. Such distortionflis guarded againstaccording to this invention, in part by the spherical taper or flange i;which stiifens the casing l and in part by giving such casing .one ormore points of internal support. Three of such supports are representedby. the pimples 22, which are punched in the rotary sleeve 5 and twoother points may be provided by allowing contact of the casing upon theupset ends of the pivot eyelets IS on the posts II.. The base end of thecasing l is stifi'ned by the inner cylinder as well as by the cap 8. Inthiswaya very light outer casing, of uniform-diameter from end to end,may be employed and even though slotted for nearly its full lengthwithout danger of such distortion as would impose an excessive frictioneither on the door members or on the keeper l of the sliding thumbpiece, which latter mustv slide freely at all times in the annularcrevice between the outer cylinder and the rotary scribed is intended.
